Water supply schemes, distribution reticulation, boreholes, and reinforced storage reservoirs
The water projects division delivers clean water supply schemes and the reticulation networks that distribute them to communities, institutions, and industrial sites.
Because our mechanical and electrical engineering departments sit under the same corporate umbrella, pump sets, solar hybrid pumping drives, automated control panels, and water treatment chlorination systems are installed directly by our in-house engineers.
We construct complete water infrastructure: high-capacity reinforced concrete reservoirs, elevated steel water storage towers, deep borehole drilling, and electrofusion-welded HDPE distribution piping.
